HC-11 CC1101 433MHz RF Serial UART Transceiver Module
The HC-11 is a 433MHz FSK wireless transceiver module based on the TI CC1101 chip, providing a simple UART/TTL serial pass-through interface for point-to-point or mesh data links. It operates from 3.3V to 5V and is configurable via AT commands for baud rate, RF power, and channel settings.
Features
- 433MHz FSK transceiver with TI CC1101 RF IC for reliable sub-1GHz communication.
- Configurable UART/TTL interface with baud rates from 1.2Kbps to 115.2Kbps for easy serial cable replacement.
- Ultra-low power operation with sleep current as low as 80μA and selectable active modes (3.5mA or 22mA).
- Adjustable RF output power up to 10dBm and high receiver sensitivity (-112dBm) for robust outdoor/indoor range.
- Compact PCB footprint (28mm x 14mm) with integrated spring antenna for quick prototyping and deployment.

The HC-11 module implements a transparent serial wireless link, converting UART data streams directly into 433MHz FSK radio packets. Its architecture centers on the proven TI CC1101 transceiver, offering stable frequency generation and configurable RF parameters including frequency deviation and receiver bandwidth. The module supports half-duplex communication, requiring a paired unit for bidirectional data transfer.
Power management is a key feature, with software-selectable modes balancing current draw against responsiveness. Engineers can fine-tune the module for battery-operated telemetry applications using AT commands, which permanently store settings in non-volatile memory. The integrated spring antenna provides adequate gain for typical indoor/urban ranges, while the module’s -40°C to +90°C operating temperature ensures reliability in industrial environments.
